I’m in bracket 2, but it is still, by far, the most common team I face. I know I give up a lot of GW bonus points, but I’ve convinced myself that the guaranteed win with reduced points is always better than a coin flip with full bonus. I posted a couple videos of me doing my GW battles last week and I was 50/50 against that team when I went for the colour bonus.
